Abstract (Dissosira) helii Yamasako et Liu, sp. nov. is described from Hainan. Mesocacia punctifasciata Gressitt, 1940 and maculifemorata Gressitt, 1940 are synonymized with Anancylus (Paranancylus) albofasciatus (Pic, 1925) and Mesosa (Aplocnemia) sparsenotata Pic, 1922, respectively. (Ipocregyes) cephalotes (Pic, 1925), Choeromorpha lineifrons (Gressitt, 1951), comb. nov., Mesosa (Aplocnemia) latifasciata (White, 1858), and Paragolsinda fruhstorferi Breuning, 1956 are newly recorded from Hainan. Consequently, a total of 21 mesosine species are known from Hainan as shown in the appended list.

Introduction

In the catalogue of Palaearctic Cerambycidae (Löbl & Smetana, 2010), twelve species of the tribe Mesosini Mulsant, 1839 were listed for the fauna of Hainan Island. Since then, Paragolsinda tonkinensis (Breuning, 1938), Spinipocregyes wenhsini Bi, 2013, basicornis Gahan, 1894, Leptomesosa langana (Pic, 1917), and Mesoereis bifasciata (Pic, 1925) were added by Yamasako and N. Ohbayashi (2011), Bi (2013), and Lin et al. (2014). As a result, 17 species of the tribe has hitherto been known from Hainan. Recently, the second author collected one unknown species on this island. After close examination, we concluded that the species in question is new to the Agelas- ta Newman, 1842. Furthermore, in the course of our survey on the Mesosini from Hainan, we recog- nized several taxonomic problems and new records. Herein, we describe a new species and newly re- cord six species with several taxonomic acts for solving taxonomic problems.

Materials and methods This study was conducted based on the dry specimens deposited in the private collections of the first and second authors (CJY, BITS) and our colleagues, Li He (CLH) and Ming Jin (CMJ), and also the following public collections: Institute of Zoology, Chinese Academy of Sciences, Beijing, China (IZAS), Musée des Confluences, Lyon, France (MHNL), Muséum National d'Histoire Naturelle, Par- is, France (MNHN), and Sun-Yat-sen University, Guangzhou, China (SYSU). Measurements of various body parts are coded as follows: LB = length of body, from the tip of vertex to elytral apex; LE = length of elytra, from the basal margin to the apex along the suture; LG = length of gena, from the upper margin to the lower margin; LL = length of lower eye lobe, from the upper margin to the lower margin; LP = length of pronotum, from the basal to the apical margin along 218 Junsuke Yamasako, Bin Liu and Mei-Ying Lin

the suture; WB = maximum width across body; WEH = width across elytral humeri; WL = width of lower eye lobe near middle; WP = maximum width across pronotum. The observational method, terminology, and abbreviations of endophallus almost follow Yama- sako and Ohbayashi (2011), but use petrolatum jelly for inflating endophallus. The abbreviations for endophallus structures used in this paper are as follows: APH: apical phal- lomer; AS: sclerite of apical phallomer; BPH: basal phallomer; CS: crescent shaped sclerites; CT: cen- tral trunk; ED: ejaculatory duct; LSp: large spicules; MPH: median phallomer; MT: medial tube; PB: pre-apical bulb; SSp: small spicules.

F e m a l e (Fig. 1d–f, n = 7): similar to male, but more rotund. LB = 14.3–17.0 mm, WB = 5.3– 6.7 mm. Antenna 1.1 times as long as body; the relative length of each segment as follows: 1.6–1.7 : 0.3 : 2.0 : 1.3–1.4 : 0.9 : 0.8 : 0.7 : 0.6 : 0.6 : 0.6 : 0.5. LL/WL = 0.8–0.9, LL/LG = 0.6–0.7. Diagnosis. This species is close to Agelasta (Dissosira) perplexa (Pascoe, 1858), but easily dis- tinguishable from the latter by having reddish brown pubescence on the body and wide transverse dark brown band on the elytra. It is also similar to Mesosa (Aplocnemia) nigrofasciaticollis Breuning, 1968 in general appearance, but different from the latter by the following characteristics: body with reddish brown pubescence; pronotum with two wide longitudinal bands on disk (M. nigrofasciaticol- lis: body with brown pubescence; pronotum with four narrow striae on disk). Distribution. China (Hainan). Etymology. The specific epithet is dedicated to Mr. Li He, who is the second author’s best friend and an experienced collector of longhorn . Remarks. This new species was first figured by Hua et al. (1993) as “Mesosa yunnana (Breun- ing)” with notes on its diagnostic features and records from Yunnan and Hainan. Later, Hua et al. (2009) cited “Mesosa yunnana (Breuning, 1938)” based on the replicated figure and diagnosis of Hua et al. (1993), and then these records were followed by Löbl and Smetana (2010). According to the figures and diagnoses in Hua et al. (1993) and Hua et al. (2009), however, “Mesosa yunnana” il- lustrated in these books are doubtlessly misidentifications of A. (D.) helii sp. nov. Mesosa (Saimia) yunnana Breuning, 1938 is notably different from A. (D.) helii by having much more elongate elytra dominantly clothed with ochre pubescence and provided with sinuate indistinct narrow black bands on basal 1/3 and apical 1/3, and so on. With this justification, the records of M. (S.) yunnana from Hainan should be removed. As a result, A. (D.) helii is found only from Hainan and M. (S.) yunnana is known only from Yunnan, China.

New Records, New Synonyms, and New Combinations

Anancylus (Paranancylus) albofasciatus (Pic, 1925) (Figs. 2k–n)

Ereis albofasciata Pic, 1925: 25. Anancylus (Paranancylus) albofasciatus: Breuning, 1939: 473. Mesocacia punctifasciata Gressitt, 1940: 120, pl. 7, fig. 2. Syn. nov. Type materials examined. Photos of a syntype of Ereis albofasciata (MNHN, Figs. 2k–l): “Dong Van / Juillet 15 / Vitalis”. Photos of the holotype of Mesocacia punctifasciata (SYSU, Figs. 2m–n): ♂, “TAI-PIN-TS’UEN / HAINAN 10 / V-1935, F. K. TO.”. Distribution. China (Hainan); Vietnam. Remarks. Mesocacia punctifasciata Gressitt, 1940 was described from Hainan under the genus Mesocacia Heller, 1926 (Gressitt, 1940). Since then, this species has been known only from Hain- an. However, based on a comparison of the type materials (Figs. 2k, 2m), it is well identical with Anancylus (Paranancylus) albofasciatus (Pic, 1925) described from N. Vietnam. Thus, M. punctifas- ciata is synonymized with A. albofasciatus herein. As a result, the genus and species are firstly re- corded not only from Hainan but also from China.

Anagelasta (Anagelasta) lineifrons Gressitt, 1951: 428, 429, pl. 16, fig.7. Type material examined. Photos of the holotype (SYSU, Fig. 2e–f): ♂, “FUKIEN / SHAOWU / TA-CHU-FUNG / VI-26–29-1943”. Specimens examined. 2 ♂♂, 5 ♀♀ (CJY), Hainan Is., China, 2007, native leg. Supplemental description. M a l e (Fig. 1g–i, n = 2): LB = 13.7–15.0 mm, WB = 5.7–6.6 mm. Antenna 1.1–1.2 times as long as body; relative length of each segment as follows: 1.7–1.8 : 0.2 : 1.4 : 1.6 : 1.2 : 0.9–1.0 : 0.7 : 0.6 : 0.5–0.6 : 0.5 : 0.5–0.6. Eyes subdivided, but upper and lower lobes con- nected a narrow line, LL/WL = 0.8, LL/LG = 0.5–0.6. Male genitalia (Fig. 4a–h, n = 2) with tegmen in dorsal view rhombic, widest just before middle, gently curved in lateral view; paramere in ventral view arcuately narrowed apically, with short setae arisen from basal 1/4 on side, which are denser and longer apically and concentrated together with long setae in apical 1/3; ringed part roundly expanded laterally before middle of tegmen, arcuately narrowed basally. Median lobe weakly curved in lateral view; basal struts bifurcated near middle; ven- tral plate with apex rounded. Endophallus about triple length of median lobe, subdivided into BPH, MPH (MT+CT and PB), and APH; BPH with pair of CS, subequal to a half length of median lobe; MPH with MT+CT 1.9 times as long as median lobe, gently narrowed in basal part; PB short, gently delated terminally; APH well swollen in bean shape, with a single ED on dorsal side near apex and a pair of rod like AS on dorsal side. LSp unidentate, arranged into two irregular lines in dorsal side of basal half of MT+CT. SSp small, unidentate, distributed in the dominant part of PB. F e m a l e (n = 5): very similar to male but relatively thick. LB = 12.8–15.4 mm, WB = 6.0–7.0 mm. Antenna 0.9–1.0 times as long as body; relative length of each segment as follows: 2.1 : 0.2–0.3 : 1.5–1.6 : 1.7 : 1.2–1.3 : 0.9–1.0 : 0.6 : 0.5 : 0.4 : 0.4 : 0.3–0.4. Distribution. China (Fujian, Hainan). Remarks. This species was originally described from Fujian, China under the genus Anagelasta Pic, 1925 by Gressitt (1951), but it is obviously different from the genus in the following character- istics: antennomere 3 shorter than 4; endophallus with AS consisted of a pair of sclerites [Anagelasta: antennomere 3 slightly longer than 4 (Breuning, 1939, Rondon & Breuning, 1970); endophallus with AS comprised of numerous sclerites aligned as a longitudinal line (Yamasako, unpub., but the endophallus of the type species, Anagelasta apicalis Pic, 1925, was figured in Yamasako & Ohbayashi, 2011)]. In addition to these characteristics, the general appearance is common to the ge- nus Choeromorpha Chevrolat, 1843 which has been distinguished from Anagelasta mainly by hav- ing antennomere 3 distinctly shorter than 4 [key to the mesosine genera in Breuning (1939) and Ron- don & Breuning (1970)]. With these reasons, this species is transferred to Choeromorpha herein. The genus and species are firstly recorded from Hainan. Notes on the Mesosini from Hainan 225

Mesosa (Aplocnemia) latifasciata (White, 1858) (Fig. 2b)

Cacia latifasciata White, 1858: 401. Mesosa (Aphelocnemia [sic]) latifasciata: Breuning, 1939: 406. Mesosa luteopubens Pic, 1917: 7 (synonymized by Breuning, 1939: 406). Mesosa latifasciata Matsushita, 1931: 44 (synonymized by Gressitt, 1951: 419). Specimen examined. 1 ♀ (CJY, Fig. 2b), Hainan Is., China, 2007, native leg. Distribution. China (Fujian, Guangdong, Guangxi, Hainan, Jiangxi, Jiangsu, Shanghai, Taiwan); Vietnam. Remarks. Although this species has been known from Southeast China and Vietnam (Gressitt, 1951; Löbl & Smetana, 2010; Lin, 2014), this is the first record from Hainan.

Mesosa (Aplocnemia) sparsenotata Pic, 1922 (Fig. 2g–j)

Mesosa sparsenotata Pic, 1922: 14. Mesosa (Aphelocnemia [sic]) sparsenotata: Breuning, 1939: 407. Mesosa maculifemorata Gressitt, 1940: 117, pl. 3, fig. 5. Syn. nov. Mesosa (Perimesosa) maculifemorata: Gressitt, 1951: 414, 420.

Type materials examined. Syntype (MNHN, Figs. 2g–h) of Mesosa sparsenotata: ♀, “Bae- quang”, “Tonkin”. Photos of the holotype of Mesosa maculifemorata (SYSU, Fig. 2i–j): ♂, “Tai-pin- ts’uen, Lam- / ka-heung, Lai-mo-Ling / (Mt. range, Kiang-shan District, May 1–4, / 1935. F. K. To”. Specimen examined. 1 ♀ (IZAS), Shifucun, Nankaixiang, Baisha County, Hainan ( 海南白沙县南 开乡什付村 ), 392 m, N19.00693/E109.36757, 15.V.2009, Xin-Lei Huang leg. Distribution. China (Hainan); Vietnam. Remarks. Mesosa (Perimesosa) maculifemorata Gressitt, 1940 was described from Hainan (Gressitt, 1940). It has been known from this island and Vietnam so far (Breuning, 1959; Löbl & Smetana, 2010). Based on a comparison of the type materials (Figs. 2g, 2i), however, M. (P.) maculi- femorata doubtlessly coincides with Mesosa (Aplocnemia) sparsenotata Pic, 1922 known from N. Vietnam. Therefore, the former is synonymized with the latter. As a result, M. (A.) sparsenotata is firstly recorded from Hainan and also from China.

Male genitalia (Figs. 4i–o, n = 1) with tegmen in dorsal view slender rhombic, widest just after middle, gently curved in lateral view; paramere in ventral view slender, gently concave at base of in- 226 Junsuke Yamasako, Bin Liu and Mei-Ying Lin ner side, weakly swollen inwardly and narrowed toward rounded apex, with short setae arisen from basal 1/3 on side, concentrated together with long setae in apical 1/4; ringed part subangularly ex- panded laterally near middle of tegmen, arcuately narrowed basally. Median lobe gently curved in lat- eral view; basal struts bifurcated near middle; ventral plate with apex roundly pointed. Endophallus about 2.5 times as long as median lobe, subdivided into BPH, MPH (MT+CT and PB), and APH; BPH with a pair of CS, slightly longer than a half length of median lobe; MPH with MT+CT 1.5 times as long as median lobe, gently curved, gradually narrowed in basal part; PB constricted in prox- imal part and delated terminally; APH well swollen in elongate ovoid shape, with a single ED on dor- sal side of terminal part and a rod like AS on dorsal side. LSp unidentate, arranged into two lines in dorsal side of basal 1/3 of MT+CT. SSp small, unidentate, dominantly covered PB. Distribution. China (Hainan); Vietnam. Remarks. This species has been known only from the type locality, Mt. Mauson, N. Vietnam (Yamasako & Ohbayashi, 2011). The genus and species are firstly recorded from Hainan and also from China. In the revision of the genus Paragolsinda Breuning, 1956 (Yamasako & Ohbayashi, 2011), no male specimen of this species was available. By this chance, we give a supplemental description with figures of the male specimen and genitalia for the first time.

山迫淳介・ 刘 彬・林 美英：海南島に分布するゴマフカミキリ族（鞘翅目カミキリムシ科）の知見およ び 1 新種．—— これまで海南島に産するゴマフカミキリ族は 17 種が知られていた．最近，海南島か ら得られた未知のゴマフカミキリ族 1 種を詳しく検討したところ，チャゴマフカミキリに近縁な新種である ことが明らかとなった．また，本種を記載するにあたり，海南島産本族について再検討を行った結果，いく つかの分類学的問題点や新記録種を見出したため，新種 Agelasta (Dissosira) helii Yamasako et Liu, sp. nov. を 記載するとともに，以下の通り整理，記録した． Cacia (Ipocregyes) cephalotes (Pic, 1925)， Choeromorpha lineifrons (Gressitt, 1951), comb. nov.， Mesosa (Aploc- nemia) latifasciata (White, 1858) および Paragolsinda fruhstorferi Breuning, 1956 を海南島から初めて記録した． これらのうち， Choeromorpha lineifrons は，これまで Anagelasta 属として扱われてきたが，外部形態および 雄交尾器の構造から明らかに Anagelasta 属とは異なり Choeromorpha 属に良く一致したため，後者に所属を 変更した．また，海南島から記載された Mesocacia punctifasciata Gressitt, 1940 および Mesosa maculifemorata Gressitt, 1940 のタイプ標本を検した結果，ベトナムから記載された Anancylus (Paranancylus) albofasciatus (Pic, 1925) および Mesosa (Aplocnemia) sparsenotata Pic, 1922 とそれぞれ同種であると結論付けた．その結果， 海南島に分布するゴマフカミキリ族は付録のリストの通り 21 種となった． 海南島のファウナは，大陸や台湾と共通するものが少なくないが，ゴマフカミキリ族も例外ではない．た Notes on the Mesosini from Hainan 227

だ し，A. (D.) helii Yamasako et Liu, sp. nov.，Cacia (Ipocregyes) nigrofasciata Gressitt, 1940 およびSpinipocre- gyes wenhsini Bi, 2013 の 3 種は，種レベルで海南島特産であり，その分布ならびに種分化を考えるうえで興 味深い．
